[Ecls-list] Any way to get stack out of condition?

[Peter Enerccio]

Well, I am trying to get with handler-bind, however, it still prints
nothing at all (for the backtrace, I mean)

(defun handle-any-error-log (e)
  (print "x") ; checking that we are indeed in the handler
  (with-open-file (eout "errors.txt"
            :direction :output)
    (format eout "Unhandled error detected: ~%")
    (format eout "~A~%" e)
    (format eout "Backtrace: ~%")
    (loop for x from (si::ihs-top)
       to 0 do
     (format eout "~A~%" (si::ihs-fun x)))
    (format eout "~%")))

(eval-when (:load-toplevel :execute)
  (handler-bind
      ((error #'handle-any-error-log))
    (post-initialization)))


Output:

enerccio at G73Jh-Arch:~/projects/gaia/gaia$ cat errors.txt
Unhandled error detected:
